'I his invention relates to Van inling de vice d and particularly to a small and compact mkn ing device adapted for use in a ticket printing and issuing machine. l

The object'ot the invention is to improve the type of inlzing device disclosed in the app 1 T plie-ation or Christopher Frederick ly/.7 ebb, Serial No. 260,268, filed March 9,1928, which shows a ticket printing and issuing machine arranged to selectively print` diile'rent types of-ticlrets trom 'a single strip, the inlring device. being arranged to inlr onlyY the plate which` is adapted to print the desired ticket. Primarily this invention haste'r its purpose the provision ofv an inlring device 'for a which is readily removis automatically released Jfrom and connected with the operating mechanism ot the ticket issuing machine.

A further obl'ect relates to the provision of an adjustable means for regulating to a fine degreethe amount ot inl: delivered by the inking roller to the printing plate.

In the accompanying drawings:

The lmain shaft of the machine indicated at be driven through. a predetermined number of cycles upon depression of a suitable key of the ticket issuing inechanism through a clutch meansfot the type disclosed in the application referred to. lThis i suitabley shape 4 on the peripheryof I serial No. 359,889.

one, designatedatt, is illustrated. Selective printing by any one of these plates is accomplished by depression oi v the proper key. A series of cams, of which l0 are a plurality of parallel rodsl2 which i; extend to the Jfront of the casing in a position The bracket easily accessible to'an operator. and rods serve as a support `tor ,the inking as'- sembly.`

rilhe linlring vassembly consistsy of a casing preferably formed ot sheet metal and which consists ot a bottom 14 integral with sides 16 and 18 and provided with front and rear flanges 20 vand 22 respectively. 'lo the rear f iange is `bolted or riveted an upwardly eX- tending plate 24 which forms the rear wall ot the casing. Similarly, to the front lange 20'there is secured a plate 26 of less rheight than plate 24 which forms the forward wall ot the casing. Each ot plates 24 and 26 extends downwardly below bottomplate 14r aswill be clear hereafter. Y A top plate 28 of as shown is provided with lugs 32 by means ot which it is pivoted between side plates 16 and 18. The portion of cover 28 extending rearwardly beyond lugs 82 is bent upwardly to a slight degree as shown. Rear plate 24 is secured so as to spring slightly in a forwardv direction vand contact with the upturned end By exerting a torce on this up-turned end above lugs 32, it will be observed that cover 28 will be releasablv held in closed position but may be raisedy against the pressure ot plate 24 when up-turned end 84 passes below the level of lugs 32 and plate 24 willv tend to hold the cover open. It can bemoved beyond this position to the indicated in dotted lines in Fig.. 3.

Pairs of aligned h les 35 are provided in 34 of the cover plate.

fully opened position which are removably secured various print- .mg plates of which eeL l and the inner end of stud the portions of plates 24 and 26 extending downwardly below plate 14. These holes are arranged so as to receive the supporting rods 12 so that the inking assembly may be slid upwardly into operative position, or downwardly te a position accessible to the operator. Extending through the lower portien of plate 26 is a stud 36 which is embraced by an elongated slot 88 in a latching plate 40. it its outer end, plate 40 is provided with a turned portion 42 which may be engaged by an operators finger to impart longitudinal sliding movement to plate 40. A lug 44 at the inner end of plate 4() extends rearwardly into a slot aligned with slot 88 so to restrain the plate from pivotal motion about stud 36 and confine it to a rectilinear sliding motion. A spring 46 secured between lug 44 86 serves to normally move the plate to the outward position shown in F ig. 4. Plate is provided with an aperture 48 which, when the pla-te is pressed inwardly against the tension of spring 46, is adapted to align with aperture 35 formed in the left hand side ef plate 26. When the plate is moved under the tension of spring 46, however, aperture 48 is out of alignment with aperture 85, as illustrated in F 4. A notch 50 provided on the inner side of the left hand rod 12 is arranged to be engaged by the periphery ef aperture 48 when the inking assembly is in position to cooperate with t'he'platen. 1t will be obvious that pressure upon end 42 of plate 40 wil-l serve to disengage the periphery of aperture' 48 from' the notch and thereby permit the assembly te be brought to accessible position. On the'other hand, in replacement of the assembly 'as the assembly slides forwardly along the rods apertures 85 and 48 will be in alignment. As soon, however, as the assembly reaches operative position, the latching plate will snap into notch 50, thereby y serving to releasably latch the assembly auto matically in proper position.

A shaft 52'journalled in walls 16V and 18, carries finedly a transfer roller 54. To the left hand end ofthis shaft is secured a crank 56 bymeans of which the shaft is driven in( a manner later described. Roller54 is arranged to carry ink from the well 55 of the shape illustrated in the drawings to an inking roller. The amount of ink thus delivered by a clockwise motion of roller 54 as viewed in Fig. 3 maybe finely adjusted by means of a plate 58 which, (s shown in Fig. 6, is provided with lugs 60 at its forward edge receivable within slots 62 in the sidewalls 16 and 18. A thumbv screw 64 passes through a hole 66 in plate 58 and is threaded into a transverse rodl 68. Byadjust-ment ofl this screw, the platemay be pivoted about lugs 60 and the engagement ofy its lade adjusted with respect tor'oller- 54. By this means a very rotate this bell crank thin film of ink may be carried by roller 54 to inking roller 72.

lnking roller 72 isrotatably mounted upon a pin 74 which has flattened ends 76 slidably' mounted in upwardly extending slot-s 78 in rthe upper portions of walls 16 and 18.

Extending outwardly-beyond flattened portions 76 are circular members 80 which are arranged to be received within hooks 82 formed at therear ends of arn'is 84. Arms 84 are rigidly joined together and to an upwardlyY extending arm 86, the arms being journalled upon a transverse bearing rod 88 so as toV form, in effect, a bell crank lever as shown in F ig. 1. A spring 90' normally servesto in a counter-clockwise direction, as viewed in Fig. 1, against a stop 92 carried by the housing of the machine. At the outer end of arm 86 there is provided a transverse pin 96 which carries cam following roller 94 adcpted to been` gaged by cams 8. This roller is of thetype disclosed in the application referred'to` above and is positioned along pin 96 in accordance with the key which is brought into line with of one of the selected rangement, during an chine, only that plate inked by roller gagement therewith by rocking of the bell crank lever by the proper cam 8.

Driving motion is imparted to transfer roller 54 through the medium of a' shaft 98 provided with which is arranged to engage 'crank 56. The type of engagement disclosed is operative even though shaft 98 is slightly out of alignment with shaft 52 `as indicated in ig. 1.` Shaft 98 is provided with a suitablesprocket wheel and is driven from the main shaft the path of movement cams 8. By this aroperation of the mawhich is to be used is through a chain which also drives the shaft carryingV the feed roller. Thus, during every rotation of shaft 2, rotary movement is 1mparted to feed roller 54, resulting in' inking u thereof and transfer of a regulated quantity of ink to inking roller 72.

By reason of the drivingl connections for shaft 52 and the hook arrangements on the ends of arms 84 engaging device is automatically broughtinto driven condition upon movement to its operative position. Likewise movement from the operative position automatically serves to diseng'age both the driving connections of shaft 52 and the lifting connections for the inking roller. Y

rlhe well 55 is preferably for the form shown and is readily removable for cleaning or replacement of ink.
